Summary

Spinal anesthesia-induced maternal hypotension during cesarean delivery is hazardous to the mother and the fetus. Prevention of the unfavorable outcomes of maternal hypotension includes various fluid and vasopressor protocols, and requires careful, frequent monitoring of blood pressure during the first 30 minutes after spinal block. Many clinicians set the blood pressure measurement intervals at 1- minute or 2-minutes intervals during the early period after spinal block. it had been reported that hypotension of duration less than 2 minutes is not harmful to the neonate; thus, the minimum inter-measurement intervals for blood pressure readings should be 2 minutes. This high frequency of blood pressure measurements commonly leads to patient dis-satisfaction due to pain as well as impairment of the interaction with the fetus after delivery. Moreover, the blood pressure measurement in the upper limbs could be affected by movement and shivering.

Using the ankle for measurement of non-invasive blood pressure (NIBP) was previously evaluated in normal subjects, and was reported to be feasible; however, its normal range differed from the arm NIBP. Under spinal anesthesia, the lower limb of the mother is neither mobile, nor sensate. Thus, it was previously hypothesized that measurement of blood pressure at the ankle of the mother could improve patient comfort. Darke and Hill had evaluated the accuracy of non-invasive blood pressure at the arm and the ankle during cesarean delivery. Darke and Hill had reported that the degree of bias between the two sites is not acceptable; however, their study did not evaluate the accuracy of ankle NIBP as a trend monitor to trace the changes in maternal blood pressure. The aim of this work is to evaluate the accuracy and precision of ankle NIBP as a trend monitor in mothers undergoing cesarean delivery under spinal anesthesia.
